u do not adjust belt tensioner if belt is loose, u need to replace belt as tensioner works automatically
The belt tensioner should have a single mounting bolt. After removing the serpentine belt, the bolt can be removed to take the tensioner off.
Remove serpentine belt. Remove alternator. The bolts that hold the tensioner on are under the alternator.
There is no adjustment you can do. It has an automatic self adjusting belt tensioner. If the belt seems to loose you may need to replace the tensioner and belt.
The job is not too hard. With the right tools, just remove the belt, and unbolt the tensioner, and replace. Then with your ratchet i( it fits in the square slot ) slack the tensioner and slip the new belt on. You have to slack the tensioner to take off the belt also.
Find the belt tensioner at the top of the belt run; it has a pulley attached to it. Insert a wrench on it and put tension against the spring loaded tensioner. Simply remove the belt and install the new one. Review the belt path before you begin the removal.

The tensioner has a spring in it that provides the correct tension for the belt. If it is too loose, replace the tensioner.
Worn belt or belt that has stretched to the point the tensioner cannot keep the proper tension. The tensioner can also be defective. Replace the belt and the tensioner.
By locating and loosening the 'tensioner' for that belt, if the alternator mount does not include a tensioner.

Disconnect the battery. Rotate the belt tensioner to release the belt. Have a helper remove the belt while holding the tensioner. Replace the belt, putting the new one on over the pulleys in the same direction. The tensioner can now be released.
